Scientists reveal why we feel pain and the consequences of life without pain. One way to understand the experience of pain is to look at unusual situations which give clues to our everyday agony.

Phantom limb pain was described in ancient times but only after WWI did it gain acceptance in modern medicine. For those living with it, it can be a painful reminder of a lost limb. New studies are now unravelling why the brain generates this often unpleasant experience and how the messages can be used positively.

Its only since the 1980s that doctors agreed that babies are able to feel pain but we still don’t know how the developing brain processes information and how premature babies can be protected from the many invasive tests they have to go through. New research aims to provide appropriate pain relief that could have long term consequences.
